Method and apparatus for producing three-dimensional objects with improved properties

摘要: A method for producing a three-dimensional object (2) by successively consolidating, layer layer, the selected areas of powder stratum, consolidated corresponding to successive sections object, said comprising following steps in order: - depositing on support; b melting means first laser-beam energy source (19) so as obtain melted section and having state mechanical properties thereof, c heating at least part using second electron-beam (20) temperature which changes time-controlled manner modify with improved properties, d repeating previous until plurality superimposed layers constituting have been formed.
